@thenardo55 Maybe you are on to something.
It could be a coincidence, but yesterday i had 0 crashes while playing several hours and was only playing with the Corvette k.s. edition. And since you can't customize anything on the k.s. edition cars, i didn't spend much time at garages.
Today i bought and customized 2 cars, but only spend like 10-15mins on each. After the first car was done my game crashed about 5 minutes after when i wanted to return to the main menu screen.
So i restarted the game, but went on with my second car, customized it and left the garage. The game crashed in less then 2 minutes.
Also, my game crashed twice in early acces with default cars, not k.s. editions. Both before just finishing a race. But i can't remember what i did before these races.
